Xeriscape: a landscaping method that employs drought resistant plants and special techniques to conserve water. I love plants! Can’t forget to do a little research on plants…
I’m thinking that someone did a pretty good xeriscape job in the Grand Canyon. Looking at the chart below with rainfall averages for the South Rim, North Rim and the Inner Gorge, I see only one month, August, with significant precipitation. The highest number for any month is 2.85 inches. The Grand Canyon is mostly desert.
In spite of that, and because of the climate changes with elevation, it is amazingly rich in plant life and almost all are drought resistant. Here’s a list:
- 1, 737 known species of vascular plants
- 167 species of fungi
- 64 species of moss
- 195 species of lichen
There are 12 plants that are only found in the Grand Canyon (endemic), and only 10% of the plants in the Canyon are exotic (from somewhere else and probably invasive). Those are pretty special statistics.
There is such a variety of eco systems in the canyon. As you can imagine, along the river where there are seeps and springs and tributaries joining the Colorado, there will be willows, acacia, rare plants and hanging gardens. At higher elevations there is desert scrub, then pinyon pine and juniper, then at about 6,500 feet above sea level the Ponderosa pine forests start. On the north rim there are some mountain meadows and subalpine grasslands.
I’m glad I don’t have to forage for food while I’m visiting the canyon, but how good is it to know that there are things there that can be eaten? I found a website telling me that the top three plants that could save me from starvation are the banana yucca, the currant bush, and the cereus cactus. Maybe you should know about them too – you never know where you’re going to find yourself. Click the link. https://grandcanyonhelicoptertour.net/top-3-edible-plants-of-the-grand-canyon/
I would have a tough time creating a xeriscape that would have the natural features and beauty of the Grand Canyon (unless I had a couple billion years to work on it) but I am expecting to enjoy and photograph it – a favorite pastime. Hoping to add some stunning pics to this post after the hike.
